how to raise humidity?

[ur420ducks]

So I just set up my 1st vert room doing barebulb with 1 1000w n 4 600w in the corners and 12 plants. I have a 9x9 room with a 1140 cfm exhaust fan with a temp controler in there as well as a heater to help keep it 75 degrees. My problem is that while the temps stay at 75 the humidity is at 30% and since im vegging I need to raise it up. The plants in there now are very small (just started today) and usually I do SOG and have a dehumidifier to keep everything in check but now its too dry sooo...
how can I up my humidity? is a humidifier the only way?
would love to hear peoples ideas thnx

Sounds to me like too much air circulation for little plants. Plants like to be in good company, and they feel best close enough to share some atmosphere. I'd just turn down the fan to where you don't need the heater, if possible.

the heater is needed because it is 40 degrees where i live and otherwise it wouldnt even get to 75 plus the fan doesnt really even run except for very lightly when it goes to like 78 n then its off again. putting them together sounds like a good idea though micro climate around em would be moister ima go do that now...

Since you're not running the exhaust fan much, a humidifier should help quite a bit.

you be surprised what a damp towel hanging on a hanger will add, atleast 5-10% RH, ive done it tons of times. its simple and it works

Bottles filled with water and a rag coming out from the top.
Misting water in to grow space.
Towels are effective too.

Those are nice DIY options.

a bin of wet perlite, simple and WAY more effective than rags, towels or even wick/fan based humidifiers. Regulate humidity by surface area of perlite, lid on/off/cracked, and airflow over surface. Say 2-4" layer of perlite, keep the water layer about halfway up. Add a few drops of bleach to prevent algae/moss etc.

TY very much m8!

I used to use a small bucket filled with water and a fish tank heater to boost the humidity...worked for me

 

[ur420ducks]

im using the towel idea now but the perlite thing sounds great ill have to try that

 

[bugler]

Hope it works well for you. Thank the old mushroom cultivation pioneers, it's standard practice in that hobby. I've also used it to humidify the house during the winter, just as effective as some commercial humidifiers I've had!

more plants!!!

Use an ultrasonic humidifier if you go that route... hard to find them with humidi-stats though.

I like that perlite trick as well, going to have to try that.

Just went to my spot & my ultra sonic ran empty god knows when, and boy were my little babies showing that they didn't like it! I filled it back up, but even with it running full steam (hehe, pun intended) it only brings it to 20-25% in there, so I added a wet towel behind the tower fan, I'll see what it's like when I get back there but I think I'll be doing the perlite trick, though the aquarium heater sounds good as well, hummmm.

Yum that is interesting but why the perlite? because it stays wet? why not just a big bucket of water, with a large surface area? peace out Headband707

No, the perlite actively wicks the moisture into the air, although that is probably a technically incorrect simple answer as it doesn't really jive with the physics of capillary action, air having no capillary capacity. Perhaps it is because the moist perlite offers more surface area than a simple bucket.

Regardless it works, it is common practice in some methods of growing fungi which require 100% humidity to use a layer of perlite across the bottom of the tub, with some amount of free water at the bottom. I guess the perlite just wicks the water into itself, and it is the greatly expanded surface area that allow more moisture to go into the air faster than just a flat surface.

I have used modifications of the typical fungi method of a full layer across the bottom of an enclosed container, and it does work and can be controlled by limiting or increasing air flow over the perlite. In situations where floor space is at a premium, I've even hung panty hose full of moist perlite to increase humidity. that situation requires daily dunking of the hose to rewet the perlite though, while a clear sided tub one can see that there is still free water available making top-ups every few days feasible as the visible free water is evaporated.

Yeah I understand lol just never thought of that ..Humity is not a problem where I live.. peace out Headband707

wheres the pics ?

How big of a tray are you using for your perlite? I've tried this in a 6x9 plastic container and my humidity doesn't do much. The area was small too (cab). Where do you position the tray?
